Command A Reasoning vs Command A Translate vs GPT-5 Chat

GPT-5 Chat is the better all-round choice, scoring 34/100 against Command A Reasoning (27) and Command A Translate (17). It leads on price, inputs & features and context window. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

GPT-5 Chat is cheaper at $1.25 input / $10.00 output per million tokens (median across 2 API providers). Command A Reasoning costs $2.50 input / $10.00 output per million tokens (official Cohere API price); Command A Translate costs $2.50 input / $10.00 output per million tokens (official Cohere API price). At a typical mix of three input tokens to one output token, that is $3.44 per million tokens for GPT-5 Chat versus $4.38 for Command A Reasoning (1.3× as much) and $4.38 for Command A Translate (1.3× as much).

There is no independent benchmark that covers all three models yet. Command A Reasoning has not been scored yet, Command A Translate has not been scored yet and GPT-5 Chat has not been scored yet.

There are no published SWE-bench Verified results for Command A Reasoning, Command A Translate and GPT-5 Chat yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that GPT-5 Chat does not support tool calling, which most coding agents need.

GPT-5 Chat has the largest context window at 400,000 tokens, against 256,000 for Command A Reasoning and 8,000 for Command A Translate. Maximum output per response: Command A Reasoning up to 32,000, Command A Translate up to 8,000, GPT-5 Chat up to 128,000 tokens.

Command A Reasoning accepts text; Command A Translate accepts text; GPT-5 Chat accepts text and images. GPT-5 Chat handles the widest range of inputs.

Command A Reasoning and Command A Translate publishes its weights and can be self-hosted; GPT-5 Chat is proprietary.

Command A Translate is the newest, released Aug 28, 2025. Command A Reasoning came out Aug 21, 2025; GPT-5 Chat came out Aug 7, 2025. Knowledge cutoff: Command A Reasoning Jun 1, 2024, Command A Translate Jun 1, 2024, GPT-5 Chat Sep 30, 2024.

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
